Once you have saved items to your Zotero Library, you can insert citations to those sources and automatically generate a bibliography in any document.
The easiest way to do this is through the Zotero plugin for Microsoft Word, LibreOffice or GoogleDocs. See the Installation page for further instructions.
You can use the Zotero plugin to add citations to your document as you write:
Once you have inserted citations, you may want to create a bibliography or Table of Authorities. Select Insert Bibliography to automatically generate a bibliography based on the sources you have cited in the document. This bibliography will automatically update to include any new citations you add later in the main text of the document.
According to the McGill Guide, you should divide your bibliography into sections (Legislation, Jurisprudence and Secondary Materials). You can manually edit these headings into your bibliography and rearrange the entries accordingly. Note: Any manual changes you make to your bibliography will disappear if you refresh or add additional in-text citations to the main text, so you should do this as the last step in finalizing your references.

York University Library's Zotero guide has additional information that is not discipline-specific.
You can use the Document Preferences button in Word to change the citation style for your entire document at any time. One click will change all citations (and any bibliography) in your document.
Note: Any citations that you have manually edited will not update automatically, so be sure to review all citations as you are finalizing the document.
